Comparative efficacy and safety of antiemetics for pediatric gastroenteritis-related vomiting in emergency departments: a network meta-analysis

Background Vomiting is a leading cause of emergency department (ED) visits among children with acute gastroenteritis (AGE). Although antiemetics are commonly used, uncertainty persists regarding the comparative efficacy and safety of individual agents across clinically relevant t...

Superior Auricular Artery Fascial Flap for Second Stage Microtia Reconstruction

INTRODUCTION: The prevalence of microtia is high among the population, and 2-stage costochondral reconstruction using the Nagata technique is widely accepted. The second stage includes elevation of the previously carved framework to create the postauricular sulcus. Many technique...

A Pilot Head-to-Head Comparison of Two Bisulfite Conversion Kits for NGS-Based DNA Methylation Analysis of Liquid Biopsy Samples from Colorectal Cancer

Given the important role of early detection in improving cancer outcomes, epigenetic alterations, particularly DNA methylation, have emerged as powerful biomarkers for cancer screening and diagnosis. However, methylation profiling of cfDNA (circulating free DNA) presents particul...

Recent Horizons in Pyridine-Based Agrochemicals (2020-2026): From Molecular Design to Ecological Safety

Abstract Pyridine derivatives have emerged as indispensable pharmacophoric scaffolds in contemporary agrochemistry, driving breakthroughs across next-generation insecticides, plant growth regulators (PGRs), micronutrient chelators, and biostimulants. This review provides a compre...

Strengthening the Genetic Evidence for the FLNA c.5776C>T (p.Pro1926Ser) Variant: Comments on Segregation, X-inactivation, and Digenic Considerations

Background: We read with interest the reported mother–daughter case series describing the novel heterozygous FLNA c.5776C>T (p.Pro1926Ser) variant associated with epilepsy and variable multisystem manifestations. Discussion: We highlight several considerations that may further st...

AMF Propagule Status Beneath Pioneer Vegetation After Two Decades of Tropical Quarry Restoration

Arbuscular mycorrhizal fungi (AMF) support plant establishment and soil recovery in degraded lands, yet their long-term associations with vegetation in restored quarries remain poorly understood. This study quantified AMF spore density and genus-level occurrence in pioneer-plant...

Epigenetic Regulation of Host Immunity During Parasitic Infections: Mechanisms, Immune Evasion, and Therapeutic Opportunities

INTRODUCTION: Parasitic infections remain a major global health challenge involving complex interactions between pathogens and host immunity. Emerging evidence indicates that epigenetic mechanisms, including DNA methylation, histone modifications, chromatin remodeling, and non-co...

Optimal design of hybrid renewable energy conversion systems using two configurations and four different algorithms for a rural village in Egypt

Abstract Decentralized energy systems can significantly enhance living circumstances in remote areas without a grid connection. This paper formulates a hybrid renewable energy model for a rural Egyptian village. The system includes PV, wind, biomass generator, battery storage, an...

A novel multi-layer security framework for medical image transmission in cloud-based wireless body area networks (BAN) using XAI-guided obfuscation and WDTW encryption

Abstract The existing frameworks for medical image encryption in the context of BANs have three major limitations: encrypting the whole image consumes enormous amount of processing time; failure to integrate explainable AI for identifying the importance of regions and prioritizin...

Photocatalytic proximity labeling for the identification of G-quadruplex DNA-interacting proteins

Abstract DNA–protein interactions play an essential role in fundamental cellular biological processes. Herein, we report a photocatalytic proximity labeling approach for the broad screening of G-quadruplex (G4)-interacting proteins (G4IPs) using human telomere G4 DNA modified wit...

Application of in vitro digestion and dialysability procedure for bioavailability evaluation of toxic elements in green leafy vegetables: a realistic health risk assessment by Monte Carlo simulation

Green leafy vegetables (GLVs), which are vital and widely consumed worldwide, require monitoring for contaminants, including toxic elements (TEs). This study measured total concentrations (TC) and bioavailable concentrations (BC) of arsenic (As), cadmium (Cd), lead (Pb), chromium...

V2X Emergency Assistance Priority — Project proposal

Project proposal. # Overview The **V2X Emergency Assistance Priority (EASP)** system uses **Vehicle-to-Everything (V2X)** communication to clear a path for emergency vehicles through congested traffic. When an ambulance, fire truck or police car is dispatched, it broadcasts its a...

Synthesis of polyhydroquinoline derivatives as potent antidiabetic and antioxidant agents: in vitro biological activities and computational studies

Aims Diabetes mellitus (DM) is a severe metabolic disease characterized by increased blood glucose levels due to reduced insulin action or secretion. This study aimed to synthesize new polyhydroquinoline (PHQ)-based acyl hydrazide derivatives and assess their potential as dual in...
